Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">

    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

    <resources os="Windows">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

    <resources os="Linux">

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

and second that this exception class cannot be found, right?

If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from

Is it expected that rxtx with native code can be run via

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

index.html:
<html>

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>

    <resources os="Windows">

    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

You wrote that you get the error:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Subject: [Rxtx] RXTXPort.close() deadlock problem and development status of
	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:

        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:

    <resources os="Linux">

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

    <resources os="Linux">

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be

This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Regards
Mariusz

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:
java version "1.6.0_20"

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I

Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

Subject: [Rxtx] clear input buffer on startup.


> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

Subject: [Rxtx] Error 0x7a on rxtx for Windows
Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

	rxtx
Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Thanks,
Marc

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

so you have two problems: first that you get a PortInUseException

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Regards
Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Subject: [Rxtx] problem upgrading from 2.1-7 to 2.2
Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Huiyan

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

Subject: [Rxtx] serial port stops working
Message-ID: <AANLkTimKJwoxk8AMpSB9Hqm_=DxnxAsKrCxLdk-V9ChN@mail.gmail.com>

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

greetings

hans

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();




Thanks!

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...
See below:

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

Subject: [Rxtx] clear input buffer on startup.
Message-ID: <8D88AEC5-C8F6-4711-B3E8-9836BFCF9605@solcon.nl>

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables

(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Subject: [Rxtx] Building RXTX 2.0 branch on Mac
Message-ID: <AANLkTikJgOdeXhk5a=PaTT8zzRSoPgkUG4ctJJWrzoVr@mail.gmail.com>

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.
http://mailman.qbang.org/pipermail/rxtx/2010-September/7821768.html

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Subject: java.lang.NoClassDefFoundError: gnu/io/PortInUseException

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>
        <jar href="RXTXcomm.jar" />
    </resources>
    <resources os="Linux">
        <nativelib href="rxtx-native-linux.jar"/>
    </resources>
    <resources os="Windows">
        <nativelib href="rxtx-native-windows32.jar"/>
    </resources>

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

The only difference is what Java I use.
I'm using RXTX version 2.2pre2.

I would be really helpful if our customers wouldn't have to install Sun's Java.

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

Thanks for the reply!

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

so I think you do get an exception.

> I'm not using webstart.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.

oki,

Steffen

Afaik the windows BT stack is the only one with both incoming and 
outgoing ports for the same device (obviously i dont know all the bt 
stacks out there, but some experience with toshiba, widcomm and bluesoleil.)
The windows bt stack is notoriously horrible, try a different one, it 
will safe you a lot of time and anguish.

Mariusz,

thanks for your answer, it pointed me in the right direction, finally I fixed the problem.
the main problem was that this.in.read(buffer) as in:

                while ( ( len = this.in.read(buffer)) > -1 )

waits until data is available and never returns -1.
But lucky me, rxtx has the function this.in.available(), which returns the amount of data available in the input.
So I made something like:
	
	while (reading) {
		if (in.available() > 0) {
			in.read(b);
			...........
		}
		yield();
	}

kindly,
Gerrit.

how can I clear the input buffer on startup,
when I open a comport on a serial device where lots of data were send to before the application opens, my application gets stuck on this data.
So how can I easily reset the port such that only new data is handled by my application?

thanks,
Gerrit.

> how can I clear the input buffer on startup,

Before opening port you are creating a new instance of the port in Java and 
OS.
In this "time point" java starts RXTX native part and this part of RXTX 
connects to device layer in OS.

Next step is opening the port.
If you have incoming data in this moment, it means that device layer don't 
cleans buffers while starting (driver's feature - programmer's 
mistake/error) or external device  is sending data and OS is receiving it.
So in fact, flushing/cleaning input buffer helps a little because you never 
don't know what has happened.

!! I haven't never seen waste data in RXTX buffer on open(), so it looks 
that RXTX and my OS drivers (FTDI) are ok. !!

What to do:
Data in EACH transmission needs header and trailer, checksum and length of 
the block are very useful as well.
If you are receiving data, you have to identify what data means - you have 
to identify block and read from this block
Your incoming part of the app should look for the first header and flush 
data until header will be identified.
Later you should wait for the trailer or read data using packet length 
(usually after header), finally check the cheksum (usually on the end, may 
be in the role of the trailer).
Succesfullly checked data should be transferred to app, damaged data should 
be flushed.

Mariusz

Hi,

My java program communicates with a device thorough USB-serial adaptor. It 
sends a command and the device sends back the information. The program is 
event based,  it works fine on Windows, but not work on MAC OS X (10.6). 
It seems that no SerialPortEvent.DATA_AVAILABLE event  was generated. I 
set a breakpoint at the start of the event handler, it didn't run to 
there. 

Has anyone met this problem before?

Thanks.

Hi Huiyan,

I know this works with some adaptors on Mac OS X.  It may be a driver 
issue.  You may check if there is an update available for the driver from 
the vendor.

hello group,

i'm using the eventbased example code from rxtx-page  to read the output of
gps-mouse.
in general the application works fine, but from time to time the serial port
stops receiving data from the mouse and doesn't recover from this state.
no exception or error is thrown.
has anyone here seen similar behaviour/problems and knows its causes and a
solution?

Message-ID: <AANLkTimNK0XVbg8R2ZZZtB0kmSNwmvfdJBJOeBm+rDsE@mail.gmail.com>

Hello,

I'm using rxtx for Windows and I got stucked on a C error.

Status:
- I'm running Windows 7
- There's a GPS device under COM4 sending stuff at 9600, 8, N, 1
- I can see the stuff sent by the device using a third-part terminal
- I run the example from the site that list all avaliable ports, and it
works fine

Problem: I run an example like the one found here (
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port).
I got the following error:

Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2263): The
transfer data space allocated for a system call is too small
Error 0x7a at /home/bob/foo/rxtx-devel/build/../src/termios.c(2269): The
transfer data space allocated for a system call is too small
(I translate the sentence "The transfer...", since some smart dude translate
the error message to portuguese)

After it, I got an gnu.io.PortInUseException

Any ideas of what is happening? The problem happens here:

import gnu.io.CommPort;
import gnu.io.CommPortIdentifier;
import gnu.io.SerialPort;

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class SerialPortRunnables
{
(...)
    void connect ( String portName ) throws Exception
    {
        CommPortIdentifier portIdentifier =
CommPortIdentifier.getPortIdentifier(portName);
        if ( portIdentifier.isCurrentlyOwned() )
        {
            System.out.println("Error: Port is currently in use");
        }
        else
        {
            CommPort commPort =
portIdentifier.open(this.getClass().getName(),2000);  //That's line 27

            if ( commPort instanceof SerialPort )
            {
                SerialPort serialPort = (SerialPort) commPort;

serialPort.setSerialPortParams(9600,SerialPort.DATABITS_8,SerialPort.STOPBITS_1,SerialPort.PARITY_NONE);

                InputStream in = serialPort.getInputStream();

Message-ID: <2CD57B12-D315-435E-B246-AA1E4058D3B3@mathworks.com>

I have an application that currently runs only on 32 bit windows and I would like to upgrade it from 2.1-7 to 2.2 in order to take advantage of the prebuilt win64 binaries.  The problem I am having is that switching my application from 2.1-7 to 2.2 causes it to stop receiving any data at all--still on windows xp 32 bit.

I work with Trent and he has been very helpful, but I still have not found the problem.  I retrieved the sources from cvs and built them.  I now have a RXTXcomm.jar modified to print to std out all the debugging information as well as a debug version of rxtxSerial.dll.

My test setup is a windows xp32 VM on a macbook talking to an embedded board via a USB serial adapter.  I realize that is a lot of intervening machinery, but everything works fine with 2.1-7.  Furthermore, I took my freshly built binaries and used them to replace the installed ones in my MATLAB R2010b.  From MATLAB, I am able to talk to my embedded board.

By not working I mean that available always returns 0 and read never reads anything.  I went through the diagnostic info printed out by rxtx and both MATLAB and my application are making all the same calls to open the serial port, configure it, and read it.

I can provide more details, code, etc. if anybody thinks it will help.  Does anyone have any idea what could be going on here?

Thanks,
Marc

Hi Mark,

How many pins are used on the embedded serial port?  I wonder if you need 
to assert DTR to enable communication.  Sometimes people resolve flow 
control problems with a blob of soldier or loopback wiring :)

The available() method is probably telling the truth.

Thinking back, I think we did turn off DTR by default because some people 
had to power cycle their devices after it was asserted.

Trent pointed out the problem to me.  Ilkka, you were right about the flow control issue.  Apparently 2.1-7 set DTR by default and 2.2 does not and this was the root cause of my problem.

Marc

I am attempting to build RXTX 2.0 from the CVS on my Mac.  I checked out the
latest version from CVS today and when I try to build, Xcode3 complains that
project.pbxproj is missing.  I compared the downloaded bits for the 2.0 and
2.1 branch and indeed project.pbxproj is missing in the 2.0 brach.  The
missing file is located in /rxtx-devel/MACOSX_IDE/Xcode3/RXTX.xcodeproj.

Can someone check this missing file in so I can build successfully?  Once
the file is checked in, I am happy to confirm if the source builds
correctly.

Thanks,
Jeff

Subject: [Rxtx] RXTX fails on Windows when Bluetooth generates two COM ports
Message-ID: <4D22FBFD.5050004@koehlers.de>

Hello RXTX- Team

as I couldn't find anything in the mail achive (?), I would like to 
highlight the following problem:

Depending on the bluetooth driver, which is supplied for an internal or 
external BT chip, Windows offers sometimes two com ports for a serial BT 
device, one for incoming connections (initiated by the BT device) and 
one for outgoing connections (initiated by the PC).

When we try to connect rxtx to the "outgoing" port, rxtx can't connect.

When we try to connect rxtx to the "incoming" port, rxtx can connect, 
but no data exchange seems to happen (which is logical in a way, because 
the simple BT device would never initiate the connection by itself, I 
assume)


Is this a known problem and is there any workaround or solution 
available to make rxtx work with such a device & driver combination?


many thanks in advance & best regards

The only difference is what Java I use.

I would be really helpful if our customers wouldn't have to install Sun's Java.

Subject: [Rxtx] win7 64-bit problems
Message-ID: <4D2C2D65.9020905@gmail.com>

Dear list members,

We are using the rxtx library in a program to connect to a Bluetooth 
peripheral device.
We have no problem in getting things to work on WinXP. Unfortunately we 
are not getting consistent results in Win7 64-bit.
I have tested it using the windows BT stack.
The connection will work sometimes, but at other times there are errors.

If connection fails for whatever reason the program will try to connect 
again a couple of times.
Sometimes we have received "No such port exceptions". These can be 
followed by a succesfull connection, but also by
> CONNECT Error 0x79 at ..\rxtx\src\termios.c(892): The semaphore 
> timeout period has expired
This will crash the program.

As I said: it does work sometimes and we never experience problems on a 
32-bit winXP system.
Is this a bug in the library? Anyone any ideas how to solve this?

Regards,

bf.

Hey bf,

I was also getting the same crashes of the RXTX.dll with Windows 7 x64. 
But only with the provided DLL.

I then built a new DLL from the newest rxtx developer source code and 
used that one. Although I'm still seeing a few termios.c errors, the dll 
doesn't crash the whole program.

Hope this helps.

Kind regards,
Helmut

Message-ID: <D2A6C675-23A5-4901-AFCD-DA02D9EEC96C@solcon.nl>

Hi all,

I'm getting desperate while trying to fix the RXTXPort.close()  deadlock problem.
When I close a port RXTX hangs.
This error is reported frequently, work arounds are published like here:
http://02-30-am.blogspot.com/2010/05/blog-post.html
and here:
http://mango.serotoninsoftware.com/forum/posts/list/297.page
and here:
http://mailman.qbang.org/pipermail/rxtx/2009-November/7747407.html

but still I didn't find a solution which works for me.

What strikes me is that although this is a well known and serious bug, which is also reported in bugzilla
(http://bugzilla.qbang.org/show_bug.cgi?id=46) still isn't fixed. 
The last stable version of rxtx is almost 5 years old now.

Is there any progress in rxtx??

kindly,
Gerrit.

Hi Gernt,
try this.- in manyl cases helps.

Look for the whole thread.
We was discussed some improvements later in the thread - but generally it 
works.

Hi,

I'm going to try with a more describing mail subject.
I'm a Java novice and really need help with this one...

Hi,

I load the native and Java lib using the jnlp script for my applet:
    <resources>

    </resources>
    <resources os="Linux">

This works fine on Windows and Linux when I'm using Sun's Java. However if I use the standard Java preinstall on Fedora, OpenJDK, I get the following error:

so you have two problems: first that you get a PortInUseException
and second that this exception class cannot be found, right?

For the first, the debug log file would be interesting. Does it
work when running the app directly on OpenJDK (w/o webstart)?

If gnu/io/PortInUseException included in any of the jar files?
If so, could it be an issue with the OpenJDK webstart itself?
Or some security/protection mechanism (such as protecting from
execution of native code libs)?

Is it expected that rxtx with native code can be run via
Webstart? How should the native lib be delivered to the JVM host?

oki,

Steffen

No, I don't get an exception. The applet fails to initialize.
I'm not using webstart.
The exception is defined in RXTXcomm.jar. (Download from the RXTX wiki page - rxtx-2.2pre2-bins.zip)

I've included the full html and jnlp file:

You wrote that you get the error:

so I think you do get an exception.

Sure that? What are you using to "process" your JNLP file?

As far as I know, usually the client browser should invoke Java
Web Start (javaws) when a JNLP (Java Network Launching Protocol)
is sent by the HTTP server. javaws should create a VM, download
and install the jars to the classloader and start the code / main.
If this raises an exception, it can be caught by the application.
However, if the exception class (file PortInUseException.class)
is not in any of the .jar files, the class loader cannot load and
instantiate the exception and instead throws a
NoClassDefFoundError exception.

I think this is what you see.
