Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers
 JD

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <40CF19D0.3090900@saadian.com>

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

can anybody tell me why RXTX is crashing at that point ? I'm not 
calling setEndOfInputChar anywhere !

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Message-ID: <1087294076.7548.55.camel@academia.thybaria.local>

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance

The longer story is that the JMRI project (http://jmri.sf.net) uses

system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Hi!

I had similar Problems with the CVS-Version from yesterday and with the
latest release version.

I am running gentoo too (for insiders: ~x86)! 

uname -a:

Linux academia 2.6.5-gentoo-r1 #6 Mon May 31 18:04:44 CEST 2004 i686
Celeron (Mendocino) GenuineIntel GNU/Linux

java -version: 

java version "1.4.2_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_04-b05)
Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Cheers,

Bernd Pachur

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much
JD Evora

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Fabien

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Java HotSpot(TM) Client VM (build 1.4.2_04-b05, mixed mode)

I do not add the error output, because it is similar to the one of Rico.
The error also occurs, when you call getReceiveTimeout().

It seems that I managed to solve the problem.

I compiled my rxtx version with debugging on and tried to find the
error.

To pin down the lines in the native code that caused the problem, I
tried to add "report(message)" lines to "NativeisReceiveTimeoutEnabled"
and "NativegetReceiveTimeout" in "SerialImpl.c" .

When I added the lines at the following location in both methods:

{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  char message[80];

  sprintf(message,"ReceiveTimeout: trace");
  report(message);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



The problem suddenly disappeared.

This combined with the fact that all problems occured on systems that
use nptl threads suggested to me, that the problem is some kind of
timing problem, when doing "tcgetattr". I then changed my addition to
the code from adding "report(messsage)" lines to adding a "usleep" line:



{
  int fd = get_java_var (env, jobj, "fd", "I");
  struct termios ttyset;

  usleep(1000);

  ENTER ("RXTXPort:NativeisRecieveTimeoutEnabled()");
  if (tcgetattr (fd, &ttyset) < 0)
    goto fail;



And guess what, the error is gone!
I don't know if this is a feasible solution on all systems, because I
normally do not code in C but in JAVA and only remeber some basics from
my C course, but at least for me it works.
It should probably be tested on other systems too before permanently
adding it to the code.

Hi,

I download rxtx-2.0-7pre1 and did a make install   it seams to install OK

I am trying to use them with a program that relays on Sun's comm API and 
when I run it I get

java.lang.NoClassDefFoundError: gnu/io/CommPort

 From the INSTALL document I saw that it happens when RXTXcomm.jar is 
not in the class path, but it is. (and in the jre/lib/ext/RXTXcomm.jar 
as well)

I opened the jar file and I didn't see the CommPort class  there are 
LPRPort*.class  and  RXTXPort*.class files  but not just a 
CommPort.class  one

Did I miss a configuration step somewhere?

Thank you very much

Hi,

If you type jar -tf RXTXcomm.jar you should have a line like this  : 
gnu/io/CommPort.class
Oh I didn?t see it. You use 2.0.x version.
You should use 2.1.x version. With this one you don?t need CommAPI from 
SUN and you put your classes in gnu/io/ whereas it?s different with 2.0.x.

Humm I hope you?ll understand what I wanted to say ^^
So use 2.1-7pre17 and everything will be ok.

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob

Hi,

Thank you for your reply.
 I used the version 2.0.x  because the library uses the Sun CommAPI on 
windows, but looks like it detects when it is running on Linux and uses 
gnu.io.* instead.
 I installed 2.1.x and it worked perfectly.

Cheers
 JD

Subject: [Rxtx] Problems with pseudo terminals on Linux
Message-ID: <00014483.40D052EA@62.153.101.193>

Hello, 

I'm a newbie to programming serial ports and to RXTX in special. I currently try to open the slave side of a pseudo terminal (/dev/ttys0) on debian linux using RXTX 2.1.6 and the BlackBox application. I've tracked my error down to the function testRead() in SerialImp.h. The OPEN call fails with errno 5 (input/output error). 

As far as I know it should be possible to open the slave side of a pseudo terminal as a regular serial port. The permissions of the slave device look also correct to me. Everybody is allowed to read or write to the device file and it belongs to root and the tty groupe.  

Can anybody help me? 

Thanks in advance 

Thomas

Hi,

I'm new to this mailing list and to rxtx

I have folowed the HOWTO install RXTX and sun's COMMAPI but it does not 
work !
I have messages as :

    root at 0[BlackBox]# java -cp BlackBox.jar BlackBox
    Exception in thread "main" java.lang.NoClassDefFoundError: 
javax/comm/PortInUseException
    root at 0[BlackBox]# java -cp /home/alex/Desktop/tini1.12/bin/tini.jar 
JavaKit   
    Exception in thread "main" java.lang.NoClassDefFoundError: 
javax/comm/CommPort
   

I tried to put comm.jar in the classpath and i get this

    root at 0[BlackBox]# java -cp 
BlackBox.jar:/home/alex/Desktop/commapi/comm.jar BlackBox
    Error loading SolarisSerial: java.lang.UnsatisfiedLinkError: no

SolarisSerialParallel in java.library.path
    Caught java.lang.UnsatisfiedLinkError: readRegistrySerial while

    No serial ports found!

I don't get what's wrong in my installation

Thanks for reply

Use version 1.1.x and replace javax/comm by gnu/io in your java programs

Subject: [Rxtx] Events on MacOS X?
In-Reply-To: <40D02294.5000200@saadian.com>

Message-ID: <p06100501bcf621414ab0@[10.0.1.4]>

Can somebody please confirm whether RXTX on MacOS X should be 
notifying about SerialPortEvents from the serial port?  I'm 
particularly interested in whether the program gets told about 
"OUTPUT_BUFFER_EMPTY" and "CTS".

The longer story is that the JMRI project (http://jmri.sf.net) uses 
RXTX to attach to various model railroad electronics.  There's one 
system, called the Lenz LI101, that requires spacing between 
messages.  We do this using the CTS and OUTPUT_BUFFER_EMPTY events, 
which works elsewhere but _not_ on MacOS X.  The current indication 
is that events just aren't being triggered.  But we don't know where 
they're being lost:  In MacOS X itself?  In the USB adapters or their 
drivers?  In RXTX?

Any pointers would be greatly appreciated.

Bob
