I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Message-ID: <6866B9FD91DFD411945C000102BEFE0E026924BB@EARTH>

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Message-ID: <4427B996.3040709@atoss-csd.de>

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers
Ludwig Wensauer

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

and comm, but the program will not work now.  I've included the error I

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Message-ID: <6866B9FD91DFD411945C000102BEFE0E026924BB@EARTH>

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Message-ID: <4427B996.3040709@atoss-csd.de>

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers
Ludwig Wensauer

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

and comm, but the program will not work now.  I've included the error I

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Message-ID: <6866B9FD91DFD411945C000102BEFE0E026924BB@EARTH>

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Message-ID: <4427B996.3040709@atoss-csd.de>

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers
Ludwig Wensauer

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

and comm, but the program will not work now.  I've included the error I

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Message-ID: <6866B9FD91DFD411945C000102BEFE0E026924BB@EARTH>

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Message-ID: <4427B996.3040709@atoss-csd.de>

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers
Ludwig Wensauer

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,

Thanks Malek

We will be incuding this in the tarball next release.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

Message-ID: <8252B48A-C8CC-40B2-82A8-3241C68478ED@mediaspansoftware.com>

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?
Thanks,

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

all of my code worked perfectly.  I now have had to move this program to a

and comm, but the program will not work now.  I've included the error I

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a

instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

See also this email linked on the front page at rxtx.org:

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"
Exception in thread "main" java.lang.UnsatisfiedLinkError:
isSessionActive
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at 
com.sun.comm.SunrayInfo.isSessionActive(Native Method)
\uffff\uffff\uffff\uffff\uffff\uffff\uffff at

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Hi Matt

"

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

Exception in thread "main" java.lang.UnsatisfiedLinkError:

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim

The summary says using more than one port causes a hang, but the  
description says the hand occurs when reading from one port and  
writing to another.  What happens if you're only reading from the two  
ports?

Just FYI: I use a Keyspan on my Mac and have successfully written to  
one port while reading from the other, as well as reading from two,  
using Rxtx 2.0.7 on 10.3.x.  I'm pretty sure I've tried 1 read & 1  
write on 10.4.x, too, but I'll double check.  I realize there's a big  
difference between 2.0.7 and 2.1.7, just providing a baseline of sorts.

Hi

Eugenia has already reported a bug:
http://bugzilla.qbang.org/show_bug.cgi?id=41

I've got the simular problem and i made some analysis which you can read 
under the bug report.
I've also sent a message to Trent, but unfortunatly he is far away from 
our earth ;)

I've send him this message here:
"...
Hello,

I've looked into the source code and i come to the following result:
the function eventLoop is the key to our success, but must i change the 
SerialImpl.c or the SerialImpl.cpp?
And Can I use the WaitCommEvent function? Or is it only a windows specific?

My other problem is, until now I weren't able to install the required 
build environment (mingw,cygwin).

btw a maybe helpfully link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnfiles/html/msdn_serial.asp 

  ..."

I hope that someone could help me.

Cheers

Hello,
	I originally developed this program using comm 2.0 for windows and
all of my code worked perfectly.  I now have had to move this program to a
CentOS 4.2 machine and needed to get a new comm package.  So I followed the
instructions on http://wass.homelinux.net/howtos/Comm_How-To.shtml
<http://wass.homelinux.net/howtos/Comm_How-To.shtml>  about installing rxtx
and comm, but the program will not work now.  I've included the error I
receive and the code it refers to.  I have not seen anything like this on
the internet or in the mail list.  Could you please help?

Hi Matt

rxtx 2.1 does not work with Sun's commapi.  It is in package gnu.io and 
works like Sun's version 2.0.  There is not way rxtx can work with Sun's 
Version 3.0 and that is supposed to be in the works to be fixed.

Basically, the project had a change in leadership at Sun and the new guy 
didn't realize how their package was being used.  Now they know and are 
fixing it but with limited resources.

You can use rxtx 2.0 with Sun's version 2.0.  Do not mix packages though. 
Either use gnu.io (rxtx 2.1) or javax.comm (rxtx 2.0, sun 2.0).

Sun does have the old 2.0 CommAPI available for download in their 
archives.  I don't have the link handy though.

Subject: [Rxtx] Changes in RXTX Leadership
Message-ID: <Pine.LNX.4.61.0603292249510.28953@www>



As mentioned earlier, I will be taking a position at The MathWorks.
Some of my duties will revolve around RXTX.  This should be a great
thing for RXTX as I will be finding and fixing bugs in a more formal
process.

In theory, there could be conflicts of interest between my job and the
RXTX community.

I will be signing a fairly typical Employment Agreement which may limit my 
ability to make the best timely decisions for RXTX should a conflict come 
up.  This is not the intent.  Carving exceptions out in legal paperwork is 
a bit cumbersome.

An easy way to solve this is to hand over primary decision making
capability to someone we all trust.  I can continue to help the project
as always but should conflicts come up, the new maintainer would have
the final say.

I've asked Dr. Douglas Lyon if he would be interested in taking this
position.  He has kindly offered to accept should we all agree.  This
should not represent a new work load for Doug.  His responsibility would
be to have the final say in disputes.  I think Doug would be excellent
for this position.  He has shown an active interest in the well being of
the RXTX project and has been working hard to make RXTX easier to
install for end users.  Perhaps this will help his work too.

It is the intent of The MathWorks and myself to do the right thing for
the RXTX community.  This is perhaps the cleanest solution which handles
any potential conflicts.  I'm rather excited about it.

If you think he is good, Trent, I trust your judgement.

Subject: [Rxtx] Problems using Serial to USB Driver under Win32
Message-ID: <OF411E7E81.7BF428A2-ONC1257142.004EB604-C1257142.004F53C2@kunden.prodigital.de>

Hello,

I am connecting to a virtual serial port on a Win32 system. The real 
device
behind this port is an USB device. Communication work fine until we 
disconnect
the USB-cable from the PC while the communication is running. In this 
moment
the communication hangs up and can not be recovered. The rxtx library 
enters
the function nativeavailable and is not returning. In the cpp-source I 
found the
following comment:

    result = PortArray[fd]->WaitForInput(); // WaitForInput() not the best 
choice, but all I could find.

Could it be that this function is not returning when the virtual port 
disappears from the
system when unplugging the USB-cable? Is the any way to avoid this 
behavior?

Regards,
Lars

I'm probably not going to be able to resolve this.

http://bugzilla.qbang.org/show_bug.cgi?id=43

Would a mail-list with just bugzilla reports be of use?

I can have a look into this but I need to get a second KeySpan  
adapter. As I dont want to buy one this could get a bit tricky...

Tim, are you shell save? If so, can you please start your application  
from a shell (ie with a full java -cp ... command), provoke the hang,  
then open a second shell. Use "ps | grep java" to find the process id  
of your java application and then use "kill -3 <process id>" to send  
it a signal.

Example

joachim$ java -cp classes:resource:lib/joelib.jar:lib/RXTXcomm.jar  
Starter

joachim$ ps | grep java
   227  p1  S+     0:01.52 java -cp classes:resource:lib/ 
joelib.jar:lib/RXTXcomm
   229  p2  S+     0:00.01 grep java
joachim$ kill -3 227

This will provide a full thread-dump of the hanging java vm. Please  
post a copy of this dump on bugzilla. It can provide some first hints  
if the problem is inside RXTX (ie a deadlock) or in the driver.

Regards,
Joachim
